The significance of biodiversity is mainly reflected in its value. For human beings, biodiversity has direct, indirect and potential use value. Direct Value:
Organisms provide human beings with food, fiber, building and furniture materials, and other raw materials for life and production. Indirect use value: Biodiversity has important ecological functions.
In ecosystems, wildlife is interdependent and mutually restrictive, and they work together to maintain the structure and function of ecosystems.
Biodiversity is an ecological term coined by Raymond in 1968. Biodiversity is the sum of the ecological complex formed by organisms (animals, plants, microorganisms) and the environment and various ecological processes related to it, including three levels: ecosystem diversity, species diversity and genetic diversity.
Biodiversity is the foundation of human survival and development, and can be conserved through in situ and ex situ conservation. Biodiversity is a broad concept that describes the diversity of species in the entire natural world, and refers to living organisms and the ecological complexes on which they exist, including the genes possessed by plants, animals, and microorganisms, and the ecosystems formed by the interaction between various organisms and the environment, as well as their bio-combustion processes. (Wang Xianpu, 1988).
Biodiversity is the diversity and variability of living organisms and the ecological complexes in which they live, including all plant, animal and microbial species and all lithostarvation systems and the ecological processes by which they form. (McNeely et al., 1990).

<> biodiversity value is mainly in the following three aspects:
1. Direct value refers to the value that has a direct impact on the social life of human beings. For example, medicinal value, ornamental value, edible value and production value of teasing reed, etc.;
2. Indirect value, which is generally manifested in water conservation, water purification, embankment consolidation, soil erosion prevention, flood peak reduction, improvement of local climate, absorption of pollutants, regulation of carbon and oxygen balance, role in regulating global climate change, mainly refers to the role of maintaining the balance of the ecosystem, etc.;
3. Potential value, which refers to the value that has not yet been discovered what effect it has on human beings or ecosystems.

Biodiversity has direct, indirect, selective, genetic and existential values, as well as huge intangible assets.
Biodiversity has a high value for development and utilization, and the development and utilization of biodiversity occupy a very important position in the economic activities of all countries in the world.
The direct value is expressed in the local consumption use value (such as food, consumption, etc.) and the production use value (wild harvest into the market).
Its indirect use value is generally manifested in water conservation, water purification, embankment consolidation, soil erosion prevention, flood peak reduction, local climate improvement, pollutant absorption, and as carbon dioxide storage in regulating global climate change, etc.
The value of choosing a block is also a potential value. Today, no one can be sure that those species that are not being used now will not be useful in the future. It is also difficult to determine how much genetic material that wild relatives of cultivated plants can provide useful for agroforestry development.
What are the levels of biodiversity?
Diversity, species diversity, and ecosystem diversity are enumerated.
For humans, the value of biodiversity lies primarily in the goods and various ecological services it provides to humans. Biodiversity not only provides indispensable biological resources for human survival, but also constitutes the biospheric environment in which human beings live. Human food is mainly based on living things, including those that live naturally and those that are cultivated artificially.
Wildlife reserves, which cover 15% of the world's land area, are threatened and biodiversity is reduced.
